3. Structure and functions of Giotto Top®
The control unit is designed to control pneumatically-operated process valves. Giotto Top®can
be equipped with a maximum of three solenoid valves to control the process valve and up to a
maximum of three inductive sensors, the third one external, to control the position.
Pneumatic connections
LEDs terminal board
Position sensor
Electrical connection
Solenoid valve
Vent valve
Anti-condensate membrane
There are three different congurations for the electrical connections inside the control unit:
LEDs terminal board:• The LEDs indicate the status of the valve, in presence of the respective
sensor: green light, valve open; yellow light, valve closed; white light, lower lift activated; blue
light, upper lift activated.
AS-i card:• the LEDs indicate the status of the corresponding solenoid valve.

5. Installation
4. Connect the electrical and pneumatic supplies.
3. Make sure the sensors are in the correct position,
otherwise adjust their height by means of the screws
on the double guide.
5. Always make sure all the wires are connected and tight in the terminals, that the solenoid valves, their sup-
port, the AS-i card and the LEDs terminal board (where installed) and other parts inside Giotto Top®are secured
rmly and assembled.
1. Open Giotto Top®and make sure the gaskets are positio-
ned correctly (21a and 21b). Screw the two screws in place
(25). Screw the cam (22).
Always MAKE SURE the electrical and pneumatic connections are NOT
activated whilst working on Giotto Top®and that the power supply voltage
is always and only 24 Vdc.
2. To t the cable gland (114c), remove the
enclosing disc of the cable gland sleeve using a
screwdriver and a mallet. Refer to the following
pages for the connection instructions.
